[PATCH v4 00/10] teach replace objects to sha1_object_info_extended()

Here is version 4 of a patch series to improve the way sha1_object_info_extended() behaves when it is passed a replaced object. The idea is to add a flags argument to it in the same way as what has been done to read_sha1_file().

This patch series was inspired by a sub thread in this discussion:

http://thread.gmane.org/gmane.comp.version-control.git/238118

The only changes compared to version 3 are the following:

	- the name of the 'full' format is now 'long'

	- the names of the replace_format enum fields
	have been prepended with 'REPLACE_FORMAT_'. This
	avoids a compilation conflict on Windows where
	SHORT is predefined. Thanks to Karsten for
	reporting this problem.

These changes only affect patches 7/10, 8/10, 9/10 and 10/10 that add a new --format option to list replace refs.

Christian Couder (10):
  Rename READ_SHA1_FILE_REPLACE flag to LOOKUP_REPLACE_OBJECT
  replace_object: don't check read_replace_refs twice
  Introduce lookup_replace_object_extended() to pass flags
  Add an "unsigned flags" parameter to sha1_object_info_extended()
  t6050: show that git cat-file --batch fails with replace objects
  sha1_file: perform object replacement in sha1_object_info_extended()
  builtin/replace: teach listing using short, medium or long formats
  t6050: add tests for listing with --format
  builtin/replace: unset read_replace_refs
  Documentation/git-replace: describe --format option
